Has anyone tried fitting a 21 inch woofer in this enclosure?
Just playing around with the idea of building this enclosure as its easier to build than the Othorn.

I started making a spacer ring a couple weeks ago to try just this. The original plan’s baffle is not deep enough — so, to prevent the driver frame from hanging out of the front of the cab, the spacer needs to be shifted off-center to the rear of the existing baffle and part of the 21” baffle cut-out ring needs to stay intact to prevent the driver from firing into the wrong part of the horn. The small part that stays intact needs to be routed/cut down to make clearance of the cone edge/surround under high drive levels. You can see some progress (I have more cutting to do) from two weeks ago (see attached). Also, my particular center brace needed quite a bit of modification to clear the bigger driver’s frame and magnet. I did not make my center brace from a cutsheet though, so you might have a different scenario.

Hi Erik! That might be pretty neat. The 21SW152 & 21DS115 sim similarly to the preferred 18” drivers, but allow much more input power before excursion is reached.
Ever hear anything from Oliver?

Cheers, all!

hi justin
i don't know what happend to oliver,i'm sort of worried too.


the driver sims best is the 21DS115-4ohm for the FT30.
it has a litle bump on 60 hz of 1 db.
it wil need a slight change in the cone correction,and the speaker baffle


could point me to olivers sub youre reffering to?


to bad youre on the other side of the pond,where i could make the pannels on my router.
grt erik
